dbg_break macro

Checking the usages of assert(0) in my code it is used to create a breakpoint in unusual situations. Sample
if (condition) {
}
else {
   assert(0); //unexpected
   return 1;
}
I am thinking in replacing all my assert(0) for this macro.
#define dbg_break(message) assert(! "dbg_break" message );
if (condition) {
}
else {
   dbg_break("unexpected");
   return 1;
}
what do you think?
Do you have any other usage of assert(0) that is not this one?
Do you have any assert(constant-expression) other than assert(0)?
